20、ated vehicles and related components.Fully Automated Coupling Systems improve safety and comfort of vehicle combinations.a) Higher safety standardsreduction of operational accidents,less injured drivers because no need for driver to stay in the dangerous zone between the towing and the towed vehicle
21、 while uncoupling.b) Higher comfort levelFully Automated Coupling Systems eliminate necessity to access the coupling,higher comfort makes “Driver-Job” easier and safer,new components create space for future extensions and potentials.c) Cost reduction for end userless inactive periods for the vehicle
22、 combination due to less damage and repair,less repair and maintenance of cables and pipes.

23、ic interface1 ScopeThis part of ISO 13044 specifies the mechanical, electrical/electronic and pneumatic characteristics of a fully automated fifth wheel coupling system to ensure interchangeability between a tractor vehicle and a coupled semi-trailer(s) with 24 V nominal supply voltage. The two vehi
24、cles together constitute an articulated vehicle.This part of ISO 13044 also supports the smooth introduction of fully automated fifth wheel coupling systems in the market. It specifies features necessary for mixed mode operation; i.e. the combination of a fully automated coupling system (FACS) equip
25、ped tractor vehicle with a conventional semi-trailer, and vice versa, the combination of a conventional tractor vehicle with a FACS-equipped semi-trailer.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its appl
